I'm having problems getting my PI System 2 dash to read the tacho signal from my 967 MBE ecu!
Have set the dash to accept 12v Pull-Up (Config C).
Have set the pulses per 2 revolutions of crank to 4.
For some reason the rpm ground connector on the back of the PI Dash has never been used to ground to a supply (car used to be a Zetec FF). Even when I earth this pin, there is no change.
Anybody any ideas ??
Cheers.
